DOORCHECK i Application led December 28, 1929.v Serial No. 417,061.

This invention relates to a door check primarily for automobiles. t Thisinvention relates'more vparticularly to that type of door check whereinthe body therethrough which is arranged to have passed therethrough arod, one end of which is pivoted to the ,door hinge pillar and the otherend of which carries a rubber blockwhich abuts against the body hingepillar at the inner end of the opening to arrestkthe outward movement ofthe door. Various means have been utilized for maintaining the rubberblock upon the end of. the rod.

It is the object of this invention to present a novel and simple meansfor adjustably maintaining the rubber blocking upon the end of the rodand this has been achieved by threading the free end of the rod andmolding a nut in be screwed upon the threaded end of the rod lto holdthe bumper in place.

In the drawings:

Fig. 1 is a section through the body pillar and door pillar showing thedoor check in the position it assumes when the door is opened. 1 l

Fig. 2 isa fragmentary elevation of the door bumper in the positionshown in Fig. 1.

Fig. 3 1s an end elevation of the bumper mounted on the rod.

Fig. 4 is a section along the line 4-4 of Fig. 3.

Referring more particularly to the drawings, the body pillar may bereferenced 1 and the body panel 2. The body pillar has n opening 3 toprovide a passageway for the loor-check rod 4. The opening 3 in the bodypillar 1 is somewhat larger in cross sectional area than the rod 4 toallow for the movement door is opened. The rod,

of the rod as the I 4 is pivoted at one end tothe bracket 5 which inturn is mounted upon the door pillar 6 by any suitable means such as therivets 7.

To prevent chattering of the rod as the door is opened and closed, awasher 8 is mounted upon`the body pillarl at the inner end ofthe opening3. y Th'e washer 8 may be retained in position by any .suitable meanssuch as the nails 9.

the rubber bumper which l front of the nut 1,2', as

The washer 8 is preferably ite. The fiber in the washer is used to givel I the washer wearing qualities and the lubricant' in turn diminisheswear on the washer.

The washer has an aperture 10 that has a slightly larger diameter thanthe diameter of the rod 4. The rod 4 is arranged to pro- 'ectp throughthe opening 10 in the washer 8. .The washer 8 is sormounted upon thebody pillar 1 that' the opening 10 therein is lo cated substantiallycentrally of the inner end of the opening 3.' Hence, therod 4 slidablyengages the washer 8 in the opening 10 and therefore is maintained inspaced relation with the sides of the opening 3.

The free end of the rod 4 is threaded as at 11 and carries thereon thenut 12. The nut 12 is molded in the rubber bumper 13 so that it isiirmly held in place. The rubber bumper 13 is provided with a suitableopening 14. The portion of the opening 14 in at 20, is of the samediameter as the. outer diameter of the threaded end of the rod, whilethe portion of the opening 14 to the rear of the nut 12, as at 21, isappreciably smaller in diameter than the outer diameter of the threadedend of the rod. Hence, when the rubber block 13 with-its molded-in nutthreaded end of the rod 4, the rubber block will yieldably engage thethreaded end of the motion. The yielding engagement is light enough topermit the block and molded-in nut to be readily turned onto the end ofthe rod 4.

Since the rubber block 13 is arranged to abut against the body pillar 1to arrest the outward movement of the door it necessarily follows thatit is subjected to rather heavy stresses at times. Hence, to properlysecure the nut 12 in the-block 13, the nut 12 is provided with asuitable annulns 15 which is recessed as at 16 to better hold it in therubber. The annular flange 15 insures the nut against being torn out ofthe rubber block 13 when the block 13 is subjected to the normalstresses and strains of use.

As shown in the full lines (Fig. 1) the door is in open position inwhich case the outward 5 movement of the door is arrested by y"thebumper 13 which abuts against the washer 8 mounted upon the body pillarl. The rela- Y. tive position of the door pillar, body illar, and thedoor-check, when the door is c osed,

1 is shown in the dotted lines (Fig. l).

It. is evident from the above description that there is here produced abumper for a door-check which is very simply, durably, and adjustablymounted upon the end of the 15 door-check rod by having the means whichsecures the bumper to the rod and which is preferably a nut, moldeddirectly in the rubber bumper. f

What I claim is:

In a door check for an automotive vehiclek having one end arranged to bepivotally mounted to the door pillar and the other end threaded andarranged Y to be projected through an opening in the adjacent bodypillar, the combination of a rubber bumper having an opening therein, apart of which is slightly smaller in diameter than the diameter of thethreaded end of the rod, a nut molded in the said rubber block with thethreaded 3 opening coinciding with the opening in the rubber blockwhereby the nut may be turned onto the threaded end of the rod so thatthe rubber block yieldably engages the threaded end of the rod toprevent relativerotation between the block and the rod owing to vehiclevibrations.

In testimony whereof I affix my signature.
